I resently watched Dirtiest Jobs with Mike Rowe on tv. They made bio deasil out of used vegetable oil.?

Has anyone ever used this with a deasil vw.I resently watched Dirtiest Jobs with Mike Rowe on tv. They made bio deasil out of used vegetable oil.?
Most people that I know do not use straight biodiesel. They blend it 60/40 50/50 with regular diesel. Any diesel engine should be able to use it.I resently watched Dirtiest Jobs with Mike Rowe on tv. They made bio deasil out of used vegetable oil.?
It's not in use here (Nebraska) unless it's mixed. Bean oil is more commonly used in Bio than waste cooking oil. The refining process for the cooking oil is more extensive than with the bean oil and the availability is much lower.


Cooking oil is more likely to have residual animal fats along with saturated fats than bean oil. Consequently the cost is bound to be prohibitive.


I wonder how a vegetarian would view this. Is it OK to burn animal fats in your diesel rather than eat animal protein. Just something to think about.
There is absolutely no risk in using biodiesel with an engine. The only thing that can possibly happen is that if you have rubber fuel lines (most pre-1996 cars) or injector pump seals, the methanol in the biodiesel can eat them away. The engine itself will remain 100% functional. There are methanol proof replacements readily available. Real B100 is vegetable oil that has been treated with chemicals to remain thin and with low viscosity but with the chemicals recovered for later use, but most B100 or B99 is actually closer to B77, the 23% or so being methanol or petroleum. The original diesel engine, as well as every other diesel built on that principle since, will run perfectly fine on vegetable oil or vegetable based fuel. In fact, that petroleum stuff they sell at gas stations and call ';diesel'; is the real alternative. Peanut oil is true diesel.
I have burned one full tank of B99 bio-diesel (that's 1% petroleum diesel and 99% vegetable oil) in my 2001 VW TDI. The motor fuel taxes were paid by the distributor on what I bought. My understanding is the veggie based fuel has stronger detergent action than petrol based fuel so you run the risk of your fuel system ingesting caked on deposits of whatever nasties might be deposited in your fuel tank, lines, filter and pump. My car ran just fine and no, it didn't smell like french fries!





Producing fuel from veggie oils requires removing the glyceryn compounds and I believe edible oil refineries use methanol for that purpose. The resulting hydrocarbon mix is fine as a fuel but lacks lubricity additives for wear resistance. Like petrol diesel fuels, those additives are added after the refining process is complete.





It is possible to burn straight veggie oil as fuel. These oils however have higher gel temperatures and thus may need to be heated in order to pass through the fuel system. Several entrepreneurs out in alternative fuel land supply conversion kits for diesel cars wanting to use straight veggie oil. They simply rout engine coolant lines to a heat exchanger in the fuel tank so excess engine heat is used to warm the fuel.





Trying the B99 is one thing but even at $4.00 a gallon for petrol diesel fuel I'm not interested in risking damage to my precious car by continuing to use some alternative that is specifically mentioned as a no-no in my VW owners manual. And at the time I tried the B99 it was about 50 cents a gallon more expensive than standard #2 petrol diesel fuel.
Some of our customers have used it, but you need to be careful.


The oil needs to be well used so getting it clean enough for modern cars is difficult.


It also needs about a cap full of some kind of spirit mixed in to help it burn.


I've seen white spirit used.


Another problem depending on where you live is that if you're caught evading fuel duty/tax you will be heavily fined
There are quite a few discussions on this topic at www.tdiclub.com I own a VW diesel, but never have used biodiesel. I am not going to risk it, nor pay more to be ';green';
